Question

♥️♥️♥️♥️heyaa! definition of cloning ( dna)​

Answer 1

Answer:Here is the answer.

DNA cloning is a term we often come across as a technique that we use in molecular biology. In this technique, a target gene ( a segment of DNA which is of interest) is inserted by various other techniques into a circular, extra chromosomal piece of DNA only, which we know as Plasmid. DNA Cloning is very significant as it helps us to create a lot of identical copies of a fragment of DNA.

Explanation:

Answer 2

• A clone is a genetically identical copy of an organism, and it may be naturally occurring or created in the lab. Through the process of asexual reproduction, organisms such as bacteria (and some plants) create offspring that are genetically identical to the parent. Modern genetic technology can also be used to create clones. There are three types of cloning: gene cloning, reproductive cloning, and therapeutic cloning. Gene cloning is essentially recombinant DNA technology, where a piece of foreign DNA is inserted into a vector, which can be copied by a host cell. Therapeutic cloning involves the production of patient-matched stem cells for disease treatment. Here we focus on reproductive cloning of organisms.

• Reproductive cloning is the process by which a whole organism is cloned. First, a cell is taken from the organism that is being cloned. The DNA from this donor cell is then transferred to an egg cell whose DNA has been removed. The egg cell is “activated” and begins dividing as if it was fertilized. An embryo results, and this embryo is then transferred to the uterus of a surrogate female. After gestation is complete, the surrogate will give birth to the clone, which is a genetic copy of the animal from which the original cell was taken.
